whom "it eoncernf sidinat Detroit., in the county of Wayne and ate 'olf gMichigan, have invented rceritain new and useful Improvements in Radia- .tors,lof.fwhich the following is a specificaytion, referencebeing hadtherein to the ari-- mi companying drawings. Y

This l 'n'vention relates. to radiators l and .more particularly to radiators for use upon -ielf-plropel'led. vehicles 4to lcool, the water 'ris circulated through'the waterfjacket vhic f of the' engine', and vitsobject is to eectually *ooolthe water assing therethrough without :retar tion-.of 1t`s circulation, and to provide 'a v simpleand cheapconstruction which 'is not repaired.

To-this end'the invention consists in so constructing the device thatthe cooling air may' pass freely between -and around the l members'forming thev water passages extendso l '. the water therein.

.. gingbetween vthe two tanks to provide .a free circulation of water, and which members are ferinedholloyv to r.provide a central passage r" :each for air, means 'being provided to positively "draw the air therethrough and `these central yair passages being continued' throughithewater tanks to assist in cooling V'lhe invention also consists in so constructing the members forming the water passages that they are cheap to manufacture, are not f llia-bleltoinjury in ordinary use or to leak,

andmaybe readily repaired if injured.`

E yA 'furtherobject is to provide a construction embodylng other certain new and use- `ful vfeatures2 all' as hereinafter more fully described reference being 'had to the accom# panying drawlng 1n which, 'Figure 1' 1s 5ar front elevation of a-device embody-ing the invention with a portion brokenawayvto Ashow the construction; Fig.

Q ,As 'shownin the drawings 1 representsA a tanks are connected yby a series of members 4 forming vertically extending water and air passages. Each of these members 1s formed by-an outer wall 5 of thm sheet 1f @settimana oftearsrateaf.' Patented rrlixlfa'na :indiane 16,1909. serial No. 502,419.

metal bent into Vshape in cross section with thelongitudinal edges 6 of the metal turned inward, and an inner wall 7 also formed,

y- \/sha ye in cross" section-with the longitudinal e ges 8 lozt the metalturned outward.v These edges 6 and 8 are soldered together thusforrnmg V-shaped tubular members, the Y space between the walls 5 and 7 lforming a water passage.' These V-shaped tubular members 4 are secured between the tanks in pairs with the open side-of the members forming each pair, adjacent to each other,

orthe inturned edges 6 in contact with each i other, the pairs of members thus forming a diamond shaped hollow member, the space or passage 9 foned .by the inner walls 7 of the two members forming an air conduit. The vertical water passages connecting the two tanks are thus formedin two parts consisting of two of the members 4, and by placing them as described, a .hollow tubular conduit is formed, the water passing freely downward from the uppertank to the lower tank through spaces between the inner and outer'walls of .the conduit and'air through' the passage formed b y the inner wall. These hollow members or conduitsvwhich are diamond shaped in cross section are secured between the tanks with their longest crosssectional diameter extendingtransversely of l thetanks and are spaced from one another a short distance to permit ythel air to pass 'freely between the same, horizontally through the radiator. A series of diamond shaped openings are provided in the bottom of the upper tank and the top of the lower tank to. receive these. members with their outer walls 5 soldered in place within the openings lso that the water in the upper tank may pass freely into the water space'and downward therethrough into the lower tank. Thei water in the upper tank is prevented from passing into the air passages 9 by a series of elbows 10 which are Vsecured with-4 in the tank 1 with their lower ends projecting intoand soldered within the upper ends of the Aair passages and their opposite ends isldered within a series of openings 11 1n the front wall 12 of the tank.

The inner wall 7 formingeach air passage 9 is extended beyondthe lower end of the wall 5, extending through the bottom of the lower water-tank 3 and soldered into openingsin said vbottom to prevent the water from entering the air passages at theirY lower ends and'to form a continuation of the air passages downward through-the lower tank, upon the bottom of which is formed 'an air' chamber 13 into which each. of the air passages open. A pipe 14 is connected to the air chamber 13 at its rear side intermediate its .ends and extends upward to a casing 15 within which is a suitable suction fan 16.

This fan may be driven in any desired man- .ner to suck the air through the tube 14,

` to the outer wall 5 of the several tubes.

In this construction the upper and lower tanks ofwthe radiator are directly connected by the vertical water passaves thus providing a free and unretarded water circulation, and by making each of the conduits hollow or with an internal air passage 9, and continuing this air passage through the upper and lower water tanks, the Vwater is eiectually cooled during its circulation as a large radiatinc area is provided "for each tube or conduit.

y providing the fan or similar means to forcibly draw the air through the inner air passages the inner walls 7 are quite as etfectually cooled b the air as are the outer walls 5 over whic the air passes on its way through the radiator between the tubes.

The shape and construction of the members 4 forming the conduits or tubes is such that they are not liable to be injured in general use as the points or apexes of the cross sections ofl the tubes extend forwardly or toward the front-of the radiator and offers strong resistance to being bent, and the several tubes may be very etfectually soldered into the tanks to make a rigid structure which is not liable to`become loosened in its joints andleak. If oneor more of the members 4 should become bent or broken the injured member may be q -uite readily removed for repair without taking the whole structure apart, Aespecially if the radiator is manufactured without the radiating tins 19.

It is obvious that changes in the minor details of construction may be made without departing from the spirit of the invention, and I therefore do lnot limit myself to any particular form or construction.

Having thus fully described my invention what-I claim is:

l. A radiator comprising water tanks having air passages extending therethrough, and a series of water conduits connecting secured to said ends, and members exten ,ser

said tanks each formed Vshape-in tion, said members being secured between.

lsaid tanks in pairs with the channeled sides of the members of each pair adjacent to each other to form a center air vpassa e extending 'm lon itudinally of each pair o said'watel conc uits and connecting the air passages extending through the tanks. i

2. A radiator comprising. tanks', and a series ot' water conducting members con` .75 necting said tanks each formed of an inner and an outer wall formed V-shaped in cross section and spaced apart, the ends of the walls being connected to form a-.water assage between the walls, and 'said mem rs 80 being arranged in pairs with the channeled sides of the members of each pair contacting to form a center air passage between eachV pair of members. j v

3. A radiator comprising an upper V`and a. lower tank, a series 'of water conducting members each formed of an inner and outer wall formed V-shaped in cross sectonand spaced apart, the longitudinal edgesof one wall being turned inward across the space between the walls to close the water passage between and the longitudinal edge ofthe other wall being turned outward over the inturned edge and secured thereto, auth-Said membersl being secured between the tanks and connected thereto at their ends and arranged in pairs with the channeled sides of the members of each pair incontact 'to form the center air passage. j

4f. A radiator comprisin an u per tank, a series of separate and in epen ent curved members within said' tank o ning at one end through the forward si e of the tank and projecting at their opposite end through the bottom of the tank, a bottom tank, a series of water conducting members each yformed with a longitudinal channelin one side and said members beingl arrangedv'in airs with the channeled sides of' the'mom ers of each pair in contact to form center air passages into the upper` ends ofwhich the lower ends of the curved-'members project,l said water `conductingl membersfbe' ing vertically through the lower tank 4and 115. forming continuations through the lower tank of the center air passages 'formed by the channeled sides of the conducting 'members.

5. A radiator comprising. an upper weber 1255s tank, a series of elbows: in said'ta'nlli s apart and openingI at one end throng front of the tank and at their o posi'te ends through the bottom of-the the lower water tank having a series of holes .its top and bottom, a series of water conducti members each formed of an outer sheet. n1 wall bent channel shape in cross sectionwth the longitudinal edges of the metal turned inward, and an innerwall formed channel 1325.
